Radeon HD 6750 1GB vs Radeon RX 6600 XT

Intro

Compare all of that to the Radeon RX 6600 XT, which has a core clock speed of 1968 MHz and a GDDR6 memory frequency of 2000 MHz. It also makes use of a 128-bit memory bus, and makes use of a 7 nm design. It is comprised of 2048 SPUs, 128 Texture Address Units, and 64 Raster Operation Units.

Radeon RX 6600 XT		160 Watts
	Difference: 74 Watts (86%)

Memory Bandwidth

The Radeon RX 6600 XT, in theory, should perform a lot faster than the Radeon HD 6750 1GB in general. (explain)

Radeon RX 6600 XT		262144 MB/sec
Radeon HD 6750 1GB		64000 MB/sec
	Difference: 198144 (310%)

Texel Rate

The Radeon RX 6600 XT should be quite a bit (about 865%) better at texture filtering than the Radeon HD 6750 1GB. (explain)

Radeon RX 6600 XT		251904 Mtexels/sec
Radeon HD 6750 1GB		26100 Mtexels/sec
	Difference: 225804 (865%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon RX 6600 XT is a better choice, by far. (explain)

Radeon RX 6600 XT		125952 Mpixels/sec
Radeon HD 6750 1GB		11600 Mpixels/sec
	Difference: 114352 (986%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Specifications

Memory Bandwidth: Memory bandwidth is the maximum amount of information (in units of MB per second) that can be transferred past the external memory interface in a second. It's worked out by multiplying the card's interface width by its memory speed. If it uses DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
